Cheesy Grilled Tomatoes

1/3 cup crumbled blue cheese
1 tablespoon olive oil
1 tablespoon chopped fresh basil
2 tablespoons grated Parmesan cheese
Heat grill. Cut tomatoes in half crosswise. With small spoon, scoop out seeds from seed cavities. Fill cavities with blue cheese. Drizzle tomatoes with oil; sprinkle with basil and Parmesan cheese. Place tomatoes cut side up, in disposable foil pie pan or on piece of heavy-duty foil.
When ready to grill, place pie pan on gas grill over medium heat. Cook 15 minutes or until tomatoes are thoroughly heated and begin to soften.
